  • Flight Or Aerial Adaptation of Birds the Following Points Highlight the Two
    Flight or aerial adaptation of birds The following points highlight the two main types of flight or aerial adaptation of birds. The types are: 1. Morphological Adaptations 2. Anatomical adaptations 1. Morphological Adaptations: Most birds possess following important flight or Volant adaptations: i. Body Contour: Because speed is a must for aerial life, so, to minimise the resistance offered by air during flight, the body of birds is fusiform or spindle-shaped and it lacks any extra projection which may offer resistance in the attainment of speed in air like fish in the water. ii. Compact Body: Their compact body is light and strong dorsally and heavy ventrally which helps in maintaining equilibrium in the air. The attachment of wings high upon the thorax, the high position of light organs like lungs and sacs, and low central position of heavy muscles, sternum and digestive organs below the attachment of both the wings and consequently low centre of gravity are other morphological facts of great significance. iii. Body-Covering of Feathers: Body of all birds is covered by special integumentary derivatives called feathers. Feathers are diagnostic of birds, since no other group of animal kingdom has ever developed them. Feathers have following advantages for birds: (a) The smooth, closely fitting and backwardly directed contour feathers make the body streamlined helping them to pass through the air by reducing the friction to the minimum. (b) The feathery covering makes the body light and at the same time protects from the hazards of environmental temperature. (c) The feathers hold a considerable blanket of enveloping air around the body and add much to its buoyancy.

Ansonia kraensis is morphologically similar to Malaysian A. malayana, but differs from it in ventral coloration and larval morphology. Occurrence of A. kraensis in this region suggests a het- erogeneous nature of the anuran fauna between northern and southern regions of the Malay Peninsula.

Assignment of larvae INTRODUCTION to the new species was based upon the occurrence of adults of that The genus Ansonia consists of small toads from South- species where the larvae were collected. We took the following 18 measurements for adult specimens east and South Asia (Frost, 2004). Members of this genus (Table 1) to the nearest 0.1 mm with dial calipers under a binocular are characterized by unique larvae that are adapted to life dissecting microscope: snout-vent length (SVL); head length (HL), in torrential streams (Inger, 1960).

Analyses of a total of 2,427 bp of the 12S rRNA, tRNAval, and 16S mitochondrial rRNA genes revealed that the two species are very close genetically. Thus A. anotis is regarded as conspecific and is synonymized with P. m a c u l a t u s . Genetically, this species proved to form a lineage distinct from other bufonids from Southeast Asia, including spe- cies of Ansonia and Pedostibes. Because the species has also some unique morphological traits different from known bufonid genera, we propose to establish a new genus for Nectophryne maculata Mocquard, 1890.

  • Larval Identities of Ansonia Hanitschi Inger, 1960 (Amphibia: Bufonidae
    Larval identities of Ansonia hanitschi and Polypedates colletti SALAMANDRA 44 2 85-100 Rheinbach, 20 May 2008 ISSN 0036-3375 Larval identities of Ansonia hanitschi Inger, 1960 (Amphibia: Bufonidae) and Polypedates colletti (Boulenger, 1890) (Amphibia: Rhacophoridae) from East Malaysia (Borneo) Alexander Haas & Indraneil Das Abstract. We describe the tadpoles of Ansonia hanitschi Inger, 1960 and Polypedates colletti (Boul- enger, 1890) from East Malaysia, Borneo. The morphological description is supplemented by photos of living specimens and SEM images of external and internal features. Identification was based on morpho- logical and genetic characters (16S rRNA). The tadpole of A. hanitschi is among the largest tadpoles de- scribed for the genus Ansonia from Borneo. This suctorial-rheophilous tadpole has been collected from fast-flowing rocky streams, in association with foaming currents. The tadpole of P. colletti is redescribed due to uncertainties about its identity and lack of photographic evidence in previous descriptions. It is an inhabitant of stagnant waters, living in and on flooded leaf litter accumulations. Key words.

  • Historical Biogeography Resolves the Origins of Endemic Arabian Toad
    Portik and Papenfuss BMC Evolutionary Biology (2015) 15:152 DOI 10.1186/s12862-015-0417-y RESEARCHARTICLE Open Access Historical biogeography resolves the origins of endemic Arabian toad lineages (Anura: Bufonidae): Evidence for ancient vicariance and dispersal events with the Horn of Africa and South Asia Daniel M. Portik* and Theodore J. Papenfuss Abstract Background: The Arabian Peninsula is home to a unique fauna that has assembled and evolved throughout the course of major geophysical events, including the separation of the Arabian Plate from Africa and subsequent collision with Eurasia. Opportunities for faunal exchanges with particular continents occurred in temporally distinct periods, and the presence of African, Western Eurasian, and South Asian derived taxa on the Arabian Peninsula signifies the complexity of these historical biogeographic events. The six true toad species (family Bufonidae) endemic to the Arabian Peninsula present a considerable taxonomic and biogeographic challenge because they are part of a global bufonid radiation, including several genera surrounding the Arabian Peninsula, and difficult to discriminate morphologically. As they could be derived from African, Western Eurasian, or South Asian toad groups, elucidating their evolutionary relationships has important implications for historical biogeography. Here, we analyze a global molecular data set of 243 bufonid lineages, with an emphasis on new sampling from the Horn of Africa, Western Eurasia, South Asia, and the Arabian Peninsula, to reconstruct the evolutionary relationships of the Arabian species. We produce a robust time-calibrated phylogeny to infer the biogeographic history of this group on and around the Arabian Peninsula. Results: Our phylogenetic analyses indicate two of the endemic Arabian toad species, “Bufo” tihamicus and “Bufo” arabicus, evolved independently within the African genus Amietophrynus.

Ansonia vidua, sp. nov., is morphologically distinguished from its Bornean congeners by the following combination of characters: medium size (SVL of adult females 33.5–34.4 mm); body uniformly black- brown in life; absence of a visible pattern on dorsum or limbs; presence of two low interorbital ridges; shagreened skin on dorsum, sides and upper surfaces of the limbs with numerous homogeneously small, rounded warts; first finger shorter than second; reduced webbing between the toes and an absence of a sharp tarsal ridge. Uncorrected genetic distances be- tween related taxa of > 4.3% in 16S rRNA gene support its status as a hitherto undescribed species.

    FULL ACCOUNT FOR: Lithobates catesbeianus Lithobates catesbeianus System: Freshwater_terrestrial Kingdom Phylum Class Order Family Animalia Chordata Amphibia Anura Ranidae Common name rana toro (Spanish), Ochsenfrosch (German), grenouille taureau (French), bullfrog (English), North American bullfrog (English), Stierkikker (Dutch) Synonym Rana catesbiana ,Shaw, 1802 Similar species Rana clamitans, Rana ridibunda Summary The American bullfrog (Lithobates catesbeianus (=Rana catesbeiana)) is native to North America. It has been introduced all over the world to over 40 countries and four continents. Many introductions have been intentional with the purpose of establishing new food sources for human consumption. Other populations have been established from unintentional escapes from bullfrog farms. Consequences of the introduction of non-native amphibians to native herpetofauna can be severe. The American bullfrog has been held responsible for outbreaks of the chytrid fungus found to be responsible for declining amphibian populations in Central America and elsewhere. They are also important predators and competitors of endangered native amphibians and fish. The control of this invasive in Europe partly relies upon increasing awareness, monitoring and education about the dangers of releasing pets into the wild. Strict laws are also in place to prevent further introductions. Eradication is achieved largely by physical means including shooting, spears/gigs, bow and arrow, nets and traps. view this species on IUCN Red List Global Invasive Species Database (GISD) 2021.
